Seriously, won't SOMEONE please take this hardware from us? We are trying desperately to give it away...

Last month PC Perspective and Hardware Canucks partnered together to offer up a March / St. Patrick's Day themed giveawawy via YouTube. The problem? Only one of 15 people I contacted about winning replied - the rest were silent or replied and did not live in the US or Canada (one of the requirements). So to fix this, we are restarting the contest for the 2nd and 3rd prize winners.

PC Perspective / Hardware Canucks YouTube Contest Follow-up

The rules are basically the same: Subscribe to both PC Perspective's and Hardware Canuck's YouTube channel, live in the US or Canada, enter by May 4th!

We'll draw the winners and notify everyone that we have done so once we have confirmation from the participants. Good luck!

ASUS MG279Q 144 Hz Display Caps at 90 Hz with FreeSync

Subject: Displays | May 1, 2015 - 04:27 PM |
Tagged: amd, freesync, asus, mg279q

Early in April ASUS and AMD announced that the MG279Q display, first shown at CES in January, would be brought into the world of FreeSync and officially adopt AMD's branding. The original post from the AMD Twitter account clearly mentions the display would support 144 Hz refresh rates, an increase from the 120 Hz that ASUS claimed during CES.

amdfs-mg279q.jpg

Now however, we have some complications to deal with. According to a FAQ posted on the ASUS.com website, FreeSync variable refresh rates will only be supported in a range of 35 - 90 Hz.

Enable FreeSync™ in the MG279’s OSD setting, choose PC’s refresh rate timing between 35-90Hz (DP/miniDP only)

On the positive, that 35 Hz lower limit would be the best we have seen on any FreeSync monitor to date. And while the 90 Hz upper limit isn't awful (considering we have seen both 75 Hz and 144 Hz limits on current monitors), it does the beg the question as to why it would be LOWER than the 144 Hz quoted maximum overall refresh rate of the display.

The ASUS MG279Q is an IPS-style display so the quality of the screen should be top notch, but that doesn't alone answer why the upper FreeSync limit and upper refresh rate would not match. We already have the Acer Predator XB270HU G-Sync display in-house that operates at a variable refresh rate as high as 144 Hz with a similar quality IPS display. I've inquired to both AMD and ASUS about the reasoning for this 90 Hz limit, and we'll see if either side cares to comment prior to the display's release.

AMD Zen Diagram Leaked and Analysis

Subject: Processors | April 27, 2015 - 06:06 PM |
Tagged: Zen, Steamroller, Kaveria, k12, Excavator, carrizo, bulldozer, amd

There are some pretty breathless analysis of a single leaked block diagram that is supposedly from AMD.  This is one of the first indications of what the Zen architecture looks like from a CPU core standpoint.  The block diagram is very simple, but looks in the same style as what we have seen from AMD.  There are some labels, but this is almost a 50,000 foot view of the architecture rather than a slightly clearer 10,000 foot view.

There are a few things we know for sure about Zen.  It is a clean sheet design that moves away from what AMD was pursuing with their Bulldozer family of cores.  Zen gives up CMT for SMT support for handling more threads.  The design has a cluster of four cores sharing 8 MB of L3 cache, with each core having access to 512 KB of L2 cache.  There is a lot of optimism that AMD can kick the trend of falling more and more behind Intel every year with this particular design.  Jim Keller is viewed very positively due to his work at AMD in the K7 through K8 days, as well as what he accomplished at Apple with their ARM based offerings.

zen.jpg

One of the first sites to pick up this diagram wrote quite a bit about what they saw.  There was a lot of talk about, “right off the bat just by looking at the block diagram we can tell that Zen will have substantially higher single threaded performance compared to Excavator and the Bulldozer family.”  There was the assumption that because it had two 256-bit FMACs that it could fuse them to create a single 512 bit AVX product.

These assumptions are pretty silly.  This is a very simple block diagram that answers few very important questions about the architecture.  Yes, it shows 6 int pipelines, but we don’t know how many are address generation vs. execution units.  We don’t know how wide decode is.  We don’t know latency to L2 cache, much less how L3 is connected and shared out.  So just because we see more integer pipelines per core does not automatically mean, “Da, more is better, strong like tractor!”  We don’t know what improvements or simplifications we will see in the schedulers.  There is no mention of the front-end other than Fetch and Decode.  How about Branch Prediction?  What is the latency for the memory controller when addressing external memory?

Essentially, this looks like a simplified way of expressing to analysts that AMD is attempting to retain their per core integer performance while boosting floating point/AVX at a similar level.  Other than that, there is very little that can be gleaned from this simple block diagram.

Other leaks that are interesting concerning Zen are the formats that we will see these products integrated into.  One leak detailed a HPC aimed APU that features 16 Zen cores with 32 MB of L3 cache attached to a very large GPU.  Another leak detailed a server level chip that will support 32 cores and will be seen in 2P systems.  Zen certainly appears to be very flexible, and in ways it reminds me of a much beefier Jaguar type CPU.  My gut feeling is that AMD will get closer to Intel than it has been in years, and perhaps they can catch Intel by surprise with a few extra features.  The reality of the situation is that AMD is far behind and only now are we seeing pure-play foundries start to get even close to Intel in terms of process technology.  AMD is very much at a disadvantage here.

Still, the company needs to release new, competitive products that will refill the company coffers.  The previous quarter’s loss has dug into cash reserves, but AMD is still stable in terms of cash on hand and long term debt.  2015 will see new GPUs, an APU refresh, and the release of the new Carrizo parts.  2016 looks to be the make or break year with Zen and K12.

Edit 2015-04-28:  Thanks to SH STON we have a new slide that has been leaked from the same deck as this one.  This has some interesting info in that AMD may be going away from exclusive cache designs.  Exclusive was a good idea when cache was small and expensive, as data was not replicated through each level of cache (L1 was not replicated in L2 and L2 was not replicated in L3).  Intel has been using inclusive cache since forever, where data is replicated and simpler to handle.  Now it looks like AMD is moving towards inclusive.  This is not necessarily a bad thing as the 512 KB of L2 can easily handle what looks to be 128 KB of L1 and the shared 8 MB of L3 cache can easily handle the 2 MB of L2 data.  Here is the link to that slide.

Some Fresh Hope for 2016

SH SOTN has some eagle eyes and spotted the latest leaked roadmap for AMD.  These roadmaps cover both mobile and desktop, from 2015 through 2016.  There are obviously quite a few interesting tidbits of information here.

On the mobility roadmap we see the upcoming release of Carrizo, which we have been talking about since before CES.  This will be the very first HSA 1.0 compliant part to hit the market, and AMD has done some really interesting things with the design in terms of performance, power efficiency, and die size optimizations.  Carrizo will span the market from 15 watts to 35 watts TDP.  This is a mobile only part, but indications point to it being pretty competent overall.  This is a true SOC that will support all traditional I/O functions of older standalone southbridges.  Most believe that this part will be manufactured by GLOBALFOUNDIRES on their 28 nm HKMG process that is more tuned to AMD's APU needs.

amd_mobile_roadmpa.jpg

Carrizo-L will be based on the Puma+ architecture and will go from 10 watts to 15 watts TDP.  This will use the same FP4 BGA connection as the big Carrizo APU.  This should make these parts more palatable for OEMs as they do not have to differentiate the motherboard infrastructure.  Making things easier for OEMs will give more reasons for these folks to offer products based on Carrizo and Carrizo-L APUs.  The other big reason will be the GCN graphics compute units.  Puma+ is a very solid processor architecture for low power products, but these parts are still limited to the older 28 nm HKMG process from TSMC.

One interesting addition here is that AMD will be introducing their "Amur" APU for the low power and ultra-low power markets.  These will be comprised of four Cortex-A57 CPUs combined with AMD's GCN graphics units.  This will be the first time we see this combination, and the first time AMD has integrated with ARM since ATI spun off their mobile graphics to Qualcomm under the "Adreno" branding (anagram for "Radeon").  What is most interesting here is that this APU will be a 20 nm part most likely fabricated by TSMC.  This is not to say that Samsung or GLOBALFOUNDRIES might be producing it, but those companies are expending their energy on the 14 nm FinFET process that will be their bread and butter for years to come.  This will be a welcome addition to the mobile market (tablets and handhelds) and could be a nice profit center for AMD if they are able to release this in a timely manner.

2016 is when things get very interesting.  The Zen x86 design will dominate the upper 2/3 of the roadmap.  I had talked about Zen when we had some new diagram leaks yesterday, but now we get to see the first potential products based off of this architecture.  In mobile it will span from 5 watts to 35 watts TDP.  The performance and mainstream offerings will be the "Bristol Ridge" APU which will feature 4 Zen cores (or one Zen module) combined with the next gen GCN architecture.  This will be a 14nm part, and the assumption is that it will be GLOBALFOUNDRIES using 14nm FinFET LPP (Low Power Plus) that will be more tuned for larger APUs.  This will also be a full SOC.

The next APU will be codenamed "Basilisk" that will span the 5 watt to 15 watt range.  It will be comprised of 2 Zen cores (1/2 of a Zen module) and likely feature 2 to 4 MB of L3 cache, depending on power requirements.  This looks to be the first Skybridge set of APUs that will share the same infrastructure as the ARM based Amur SOC.  FT4 BGA is the basis for both the 2015 Amur and 2016 Basilisk SOCs.

Finally we have the first iteration of AMD's first ground up implementation of ARM's ARMv8-A ISA.  The "Styx" APU features the new K12 CPU cores that AMD has designed from scratch.  It too will feature the next generation GCN units as well as share the same FT4 BGA connection.  Many are anxiously watching this space to see if AMD can build a better mousetrap when it comes to licensing the ARM ISA (as have Qualcomm, NVIDIA, and others). 

The Desktop

2015 shows no difference in the performance desktop space, as it is still serviced by the now venerable Piledriver based FX parts on AM3+.  The only change we expect to see here is that there will be a handful of new motherboard offerings from the usual suspects that will include the new USB 3.1 functionality derived from a 3rd party controller.

amd_desktop_roadmap.jpg

Mainstream and Performance will utilize the upcoming Godavari APUs.  These are power and speed optimized APUs that are still based on the current Kaveri design.  These look to be a simple refresh/rebadge with a slight performance tweak.  Not exciting, but needs to happen for OEMs.

Low power will continue to be addressed by Beema based APUs.  These are regular Puma based cores (not Puma+).  AMD likely does not have the numbers to justify a new product in this rather small market.

2016 is when things get interesting again.  We see the release of the FM3 socket (final proof that AM3+ is dead) that will house the latest Zen based APUs.  At the top end we see "Summit Ridge" which will be composed of 8 Zen cores (or 2 Zen modules).  This will have 4 MB of L2 cache and 16 MB of L3 cache if our other leaks are correct.  These will be manufactured on 14nm FinFET LPE (the more appropriate process product for larger, more performance oriented parts).  These will not be SOCs.  We can expect these to be the basis of new Opterons as well, but there is obviously no confirmation of that on these particular slides.  This will be the first new product in some years from AMD that has the chance to compete with higher end desktop SKUs from Intel.

From there we have the lower power Bristol Ridge and Basilisk APUs that we already covered in the mobile discussion.  These look to be significant upgrades from the current Kaveri (and upcoming Godavari) APUs.  New graphics cores, new CPU cores, and new SOC implementations where necessary.

AMD will really be shaking up the game in 2016.  At the very least they will have proven that they can still change up their game and release higher end (and hopefully competitive) products.  AMD has enough revenue and cash on hand to survive through 2016 and 2017 at the rate they are going now.  We can only hope that this widescale change will allow AMD to make some significant inroads with OEMs on all levels.  Otherwise Intel is free to do what they want and what price they want across multiple markets.

Samsung 840 EVO Standalone ISO Updater Now Available

Subject: Storage | April 28, 2015 - 12:44 PM |
Tagged: TurboWrite, tlc, ssd, slc, Samsung, 840 evo

For those of you following the Samsung 840 EVO saga, last week we saw the release of Magician 4.6. Samsung was initially throttling downloads and firmware update rates, but those limits appear to have been lifted as of this morning. Another thing we noticed this morning was the inclusion of the standalone ISO updater for those who are otherwise unable to run the Magician software (i.e. Mac users):

EXT0DB6Q ISO.png

For those on laptops or other devices with no optical drive, I've confirmed the ISO can be used via USB if placed there with a tool such as Rufus.

Note to Linux users:

There was an early report of complications from a user who was running a full disk fstrim during boot, where that operation was causing errors (corrected once that operation was disabled). It should be noted that full disk TRIM operations are redundant so long as the OS is issuing TRIM on-the-fly during regular file moves / deletions. This may be an issue with queued TRIM handling of the new 840 EVO firmware. If not reproduced / corrected by Samsung, the Linux devs may be able to add this firmware revision to the queued TRIM blacklist to possibly fix the problem on their end.

Note to mSATA 840 EVO users:

It appears the update does not currently apply to these. I've asked Samsung about this.

Don't be afraid of PCIe or NVMe

In very early April, Intel put a shot across the bow of the storage world with the release of the SSD 750 Series of storage devices. Using the PCI Express bus but taking advantage of the new NVMe (Non-Volatile Memory Express) protocol, it drastically upgrades the capabilities of storage within modern PC platforms. In Allyn's review, for example, we saw read data transfer rates cross into the 2.6 GB/s range in sequential workloads and write rates over 1.2 GB/s sequentially. Even more impressive is the random I/O performance where the SSD 750 is literally 2x the speed of previous PCIe SSD options.

IMG_2051.JPG

A couple of weeks later we posted a story looking into the compatibility of the SSD 750 with different motherboards and chipsets. We found that booting from the SSD 750 Series products is indeed going to require specific motherboards and platforms simply due to the "new-ness" of the NVMe protocol. Officially, Intel is only going to support Z97 and X99 chipsets today but obviously you can expect all future chipsets to have proper NVMe integration. We did find a couple of outliers that allowed for bootability with the SSD 750, but I wouldn't count on it.

Assuming you have a Z97/X99 motherboard that properly supports NVMe drives, of which ASUS, MSI and Gigabyte seem to be on top of, what are the steps and processes necessary to get your system up and running on the Intel SSD 750? As it turns out, it's incredibly simple.

Step 1

Make sure you have enabled NVMe in the latest BIOS/UEFI. The screenshot below shows our ASUS X99-Deluxe motherboard used during testing and that it is properly recognizing the device. There was no specific option to ENABLED NVMe here though we have seen instances where that is required.

ASRock EPC612D4I Motherboard: Mini-ITX LGA 2011-3 with Quad-Channel DDR4

Subject: Motherboards | May 1, 2015 - 09:25 AM |
Tagged: sodimm, quad-channel, mini-itx, EPC612D4I, ddr4, ASRock Rack, asrock

They finally did it! A new mini-ITX LGA 2011-3 has been announced by ASRock, the EPC612D4I, and this server-grade product will offer full quad-channel memory support with a switch to SoDIMM RAM.

EPC612D4I-R1.00_45.jpg

While ASRock had previously released a mini-ITX X99 motherboard (the X99E-ITX/ac) there were concessions made based on the limitations of the form-factor, and the motherboard was limited to dual-channel memory with only two DDR4 DIMM slots. So for a full quad-channel experience it became obvious that a switch to SoDIMM’s would be required. So are there any DDR4 SoDIMMs available? They certainly aren’t cheap, but a quick search for the model number of this new board finds a page from Crucial for compatible DDR4 modules – at a cost of $555.99 for a massive 32GB (4x8GB) of 1.2V DDR4-2133 ECC memory.

Specs for the EPC612D4I from ASRock:

  • LGA 2011 R3 Intel Xeon processor E5-1600/2600 v3 series
  • 4x SO-DIMM slots, supports quad-channel DDR4 2133/1866 ECC
  • 4x SATA 6Gb/s by C612
  • 1x PCIe 3.0 x16                      
  • Integrated IPMI 2.0 with KVM and Dedicated LAN (RTL8211E)
  • Intel Dual GLAN (Intel i210 + Intel i217)

The new board was first reported by Tom's IT Pro and their article lists the retail price for the ASRock EPC612D4I at $265, which isn’t bad for a product like this. While definitely targeting the server market this could potentially be implemented for a very compact workstation setup (and allow creation of a PC to rival the diminutive Mac Pro, perhaps).

BUILD 2015: Windows 10 10074 Released to Fast and Slow

Subject: General Tech | April 30, 2015 - 06:38 PM |
Tagged: windows 10, microsoft, build 2015, build 10074, BUILD

When Microsoft forked their build numbers into 100xx and 101xx lines, we predicted that they were preparing a version to release at BUILD 2015. We also predicted that it would be heavily tested and pushed to both Slow and Fast simultaneously, which would give a good entry point for developers and probably even enterprise evaluators. I was surprised when Microsoft released 10061 last week, and then updated it just two days ago (why???) with four patches, but we ended up being correct in the end.

windows-10.png

Microsoft has just released Windows 10 build 10074 to both Fast and Slow users. Its comes with a very small list of known issues, and they are much less severe than they were in previous releases. The first issue tells developers that Developer Mode needs to be enabled in Group Policy, rather than the place in Settings that it will eventually be. The next two issues are more severe: some games cannot be played in full screen and the People app is still broken. I am not sure how wide-spread “some games” is, but they plan to patch it via Windows Update “as soon as possible”.

One major fix is that now, when certain applications that play audio are minimized, they will continue to play audio. This bug made many media players, such as a few SoundCloud apps in the Windows Store as well as Microsoft's own Music app, pretty much useless. Until 10074, you would basically need to launch them, then cover them up with other windows if you wanted more screen real-estate.

microsoft-windows10-10074-start.jpg

If you were a fan of Aero from Windows 7, then you will like the blurred transparency effect of Start and the taskbar. Personally, while I think it looks nice, I was never really attached to that aspect of the Windows UI. Honestly, it used to drive me nuts when it kicked me out of games to complain about how it cannot properly manage 2GB of video memory, despite running perfectly fine if I select ignore. Hopefully that will not come back with it. But, if it is here without causing any problems, it does look pretty. Also, the Start Menu can now be manually resized to better arrange your apps. It also looks like the semi-horizontal layout is a great compromise between the Start Menu and the Start Screen for desktops.

So, as we expected, this build is what happens when Microsoft picks a target and mostly cleans up all of their relevant branches into a solid release. It is still a bit buggy here and there, but it feels better than 10049, which was itself better than 10041. That said, I also upgraded my NVIDIA drivers from 349.90 to 352.63; that could have something to do with it (although I am using the same Intel drivers).

There has not been too many announcements regarding features that are not present in 10074 though. It makes you wonder, at least a bit, how much will be added to the 101xx path until the OS finally launches.

ARM Releases Cortex-A72 for Licensing

On February 3rd, ARM announced a slew of new designs, including the Cortex A72.  Few details were shared with us, but what we learned was that it could potentially redefine power and performance in the ARM ecosystem.  Ryan was invited to London to participate in a deep dive of what ARM has done to improve its position against market behemoth Intel in the very competitive mobile space.  Intel has a leg up on process technology with their 14nm Tri-Gate process, but they are continuing to work hard in making their x86 based processors more power efficient, while still maintaining good performance.  There are certain drawbacks to using an ISA that is focused on high performance computing rather than being designed from scratch to provide good performance with excellent energy efficiency.

arma72_01.jpg

ARM has been on a pretty good roll with their Cortex A9, A7, A15, A17, A53, and A57 parts over the past several years.  These designs have been utilized in a multitude of products and scenarios, with configurations that have scaled up to 16 cores.  While each iteration has improved upon the previous, ARM is facing the specter of Intel’s latest generation, highly efficient x86 SOCs based on the 2nd gen 14nm Tri-Gate process.  Several things have fallen into place for ARM to help them stay competitive, but we also cannot ignore the experience and design hours that have led to this product.

(Editor's Note: During my time with ARM last week it became very apparent that it is not standing still, not satisfied with its current status. With competition from Intel, Qualcomm and others ramping up over the next 12 months in both mobile and server markets, ARM will more than ever be depedent on the evolution of core design and GPU design to maintain advantages in performance and efficiency. As Josh will go into more detail here, the Cortex-A72 appears to be an incredibly impressive design and all indications and conversations I have had with others, outside of ARM, believe that it will be an incredibly successful product.)

 

Cortex A72: Highest Performance ARM Cortex

ARM has been ubiquitous for mobile applications since it first started selling licenses for their products in the 90s.  They were found everywhere it seemed, but most people wouldn’t recognize the name ARM because these chips were fabricated and sold by licensees under their own names.  Guys like Ti, Qualcomm, Apple, DEC and others all licensed and adopted ARM technology in one form or the other.

arma72_02.jpg

ARM’s importance grew dramatically with the introduction of increased complexity cellphones and smartphones.  They also gained attention through multimedia devices such as the Microsoft Zune.  What was once a fairly niche company with low performance, low power offerings became the 800 pound gorilla in the mobile market.  Billions of chips are sold yearly based on ARM technology.  To stay in that position ARM has worked aggressively on continually providing excellent power characteristics for their parts, but now they are really focusing on overall performance and capabilities to address, not only the smartphone market, but also the higher performance computing and server spaces that they want a significant presence in.

Godavari rumours abound

Tagged: Summit Ridge, rumours, Godavari, Bristol Ridge, amd

This morning DigiTimes is reporting on a unconfirmed rumour that AMD's new APU, Godavari, will be arriving towards the end of May of this year.  This goes along with the leak that WCCFtech reported on this weekend, they have information that the chip will be a Kaveri design with up to four Steamroller cores, a GCN 1.1 base GPU with up to 512 stream processors and a dual-channel DDR3 memory in an FM2+ socket.  If their information is accurate you can expect to see models with 65W or 95W TDPs and boost clocks in the 4GHz range depending on the model.  Also worth noting is the rumour that AMD has placed orders with ASMedia Technology for USB 3.1 controller ICs for release in September.

Kubuntu drops the old KDE for the new Plasma 5 desktop environment

Tagged: plasma, linux, kubuntu

Kubuntu came about when Ubuntu switched to the Unity desktop environment as a KDE based alternative, which as Linux.com points out caused much disgust due to bugs at launch and a less than attractive interface.  The newest version now uses the Plasma 5 environment, the first release to do so, replacing version 4 which has been in use almost decade now.  This distro still uses Dolphin as its file manager but now uses Simple Desktop Display Manager (SDDM) instead of KDM.  It also incorporates systemd, with these two changes users of Arch Linux will feel right at home.  Check out the review for a list of the programs it ships with as well as the ones that Linux.com added after the fact to make Kubuntu work best for their machines.

Samsung's Galaxy refresh refreshes a bit too often

Tagged: Samsung, galaxy s6, Galaxy S6 Edge

No company wants to hear their new flagship product has issues but unfortunately that has become all too common as financially gifted and tattooed Apple fans are well aware.  It would seem that Samsung is also having launch pains as users are seeing problems with RAM allocation.  The Inquirer reports that the phone will use up to 2.5GB for simple tasks, with Chrome being a major memory thief.  The programs do still run and the issue is not causing crashes, instead you can expect to see some stuttering and a lot of refreshes when you return to an app that has lost focus, even for a short time.  Samsung is aware of the problem and working on incremental updates which you can pick up via Update Now under Settings.

NZXT Announces the Noctis 450 Gaming Mid-Tower Enclosure

Subject: Cases and Cooling | April 28, 2015 - 09:29 PM |
Tagged: nzxt, Noctis 450, mid-tower, enclosure, case

NZXT proclaims that “bold is back” with their new enclosure design, a striking-looking case based (at least internally) on the popular H440.

Noctis-450-2560x1600-black2.jpg

The Noctis 450 takes the H440 and combines it with an angular external construction that looks similar to the company’s Phantom enclosure series. As the interior is identical to the H440 this new enclosure features the spacious interior and excellent cooling support from the previous model. As a nice addition the Noctis 450 adds a PWM fan controller (and includes 4 fans), further simplifying cooling for a build with this case.

NZXT has created a product video to showcase the new design:

In the appearance department the Noctis 450 really does look good (although style is always a personal thing), with dramatic black/red and the familiar NZXT white/black color schemes available to help accent the interesting angles, and there is an adjustable LED lighting system as well.

Plenty of storage room (unless you're Allyn) with 5 slide-out HDD trays

The MSRP is set at $139.99 and the Noctis 450 is currently available for pre-order on the NZXT site.

G.Skill's Ripjaws 4; fast and relatively affordable memory for your Haswell-E system

At $450 for 16GB of DDR4-3200, G.Skill's Ripjaws 4 kit is very well priced for DDR4 of that speed, especially if you like the active cooling fans.  This particular kit is has timings of 16-16-16-36 with a 2T command rate. It also requires an impressive 1.35V to hit full speed, well above the 1.2V specification but in line with many of the other DDR4 enthusiast kits.  Indeed when Hardware Canucks started their overclocking tests they raised that to 1.4V and managed a variety of tighter timings with reduced clock speed; worth noting is that all of those overclocks were successful when using a 1T command rate.  Check out their full review here and don't forget to sign up for our contest!

Cirrus7 Shows Off Fanless Nimbini Broadwell NUC PC

Next month, German manufacturer Cirrus7 will begin shipping its new Nimbini system. The Nimbini is an even smaller variant of the company’s small form factor Nimbus PC. This time, Cirrus7 has managed to pack a Intel NUC system into a fanless case with multiple layers of stacked laser cut aluminum panels that double as a heatsink for the internals. Even better, the Nimbini supports Intel’s Rock Canyon and Maple Canyon NUC boards, and supports Broadwell-U processors up to the 28W Core i7 models with Iris Graphics (e.g. the two core, four thread, Core i7-5557U with Iris Graphics 6100).

The Nimbini will come as a complete system (150 x 150 x 87mm) preloaded with Windows or Ubuntu Linux operating systems or as a barebones DIY kit – which at upwards of 90 pieces (per FanlessTech) is not for the faint-of-heart! This case can be customized to add different covers and to vary the thickness of the case by adding or removing layers. The standard configuration leaves room for a 2.5” drive in addition to the usual M.2 SSD used with NUCs. If you aren’t using that second storage drive, you can make the case thinner or expand it for maximum cooling. While also aesthetically pleasing, the best part about the aluminum construction is that it is a fanless design which is perfect for a HTPC (home theater PC) or audio engineering setup. Cirrus7 claims to support up to 28W processor TDPs without any fans.

Cirrus7 will being taking pre-orders in May. Among others, both the Rock Canyon (with its IR receiver and accompanying case window) and Maple Canyon internal hardware (NUC boards) with dual DisplayPort outputs will be on offer. Pricing has not yet been announced, but it looks promising if you are looking for a premium silent SFF PC.

Scythe Ninja 4 Cooler Expected to Be Active or Fanless

Subject: Cases and Cooling | April 26, 2015 - 02:37 PM |
Tagged: fanless, cooler

We are getting a fair amount of “big heatsink” options for enthusiasts, which is nice. This one is from a Japanese manufacturer, Scythe Co., and it's quite big. It is similar in size and weight to the Noctua D14, but in a four-tower design. Each stack of fins has three heat pipes, twelve fingers total, to deliver the heat up from the plate that rests on your CPU. It measures 13cm x 15.5cm x 15.3cm and weighs 0.9kg.

The product page doesn't seem to declare a fanless operation mode, but FanlessTech mentions that previous models were advertised at, not just abused by enthusiasts to, 65W in passive configurations. It is a pretty large cooler, so that makes sense. I have also seen a few posts where the Noctua D14 can be used fanless for around 65W. You cannot really make an apples-to-apples comparison between the two units though. While the size and weight are similar, the geometry is quite different. For example, the Noctua is really designed to have fans installed between the two towers as well as the ends, blowing air over the fins in a certain direction.

No news about pricing or availability for Europe or North America yet. The company does have an international presence though.

Introduction and Features

Introduction

2-Banner.jpg

SilverStone has a long-standing reputation for providing a full line of high quality enclosures, power supplies, cooling components, and accessories for PC enthusiasts. With a continued focus on smaller physical size and support for small form-factor enthusiasts, SilverStone recently introduced the new SX500-LG. There are currently five power supplies in the SFX Series, ranging in output capacity from 300W to 600W. The SX500-LG is the first one to feature an extended chassis. The SX500-LG enclosure is 30mm (1.2”) longer than a standard SFX chassis, which allows using a quieter 120mm cooling fan rather than the typical 80mm fan used in most SFX power supplies.

3-Compare.jpg

150mm                                130mm                              100mm

The new SX500-LG SFX-L Series power supply was designed for small form factor cases but comes with an ATX adapter plate so it can be used in a standard ATX enclosure as well. In addition to its small size, the SX500-LG features high efficiency (80 Plus Gold certified), all modular flat ribbon-style cables, and provides up to 500W of continuous DC output. The SX500-LG PSU also operates in semi-fanless mode (cooling fan turns off at low power).

Note: We have seen rumors on the web about the new SX500-LG power supply being a re-packaged version of the SX600-G that SilverStone recalled awhile back. Rest assured it is not. The SX600-G is a completely different PSU made by Enhance and the new SX500-LG is made by High Power. And yes, the SX500-LG is officially listed as an 80 Plus Gold certified PSU (10-22-2014).

Here is what SilverStone has to say about the new SX500-LG PSU: “For small form factor enthusiasts, the standard SFX power supply form factor has an excellent combination of size, power, and affordability. At 100mm deep, however, the standard SFX PSU is also limited in fan size to 80mm. While advances in engineering and components have modern high-end SFX PSUs quieter than ever, there is still inherent limitation with 80mm fan’s ability to dissipate heat at maximum loading conditions while maintaining satisfactory noise profile for users sensitive to higher-pitch sounds. With this in mind, SilverStone has released a “lengthened” variation of the SFX form factor called, SFX-L. With 30mm of added depth, a SFX-L power supply has enough room to fit a 120mm fan, thus its maximum load noise can be not only lower in intensity (via slower fan speed), but also lower in pitch (due to larger fan size). The first model to debut in the SFX-L will be the SX500-LG, a 500W model that includes all features available from top of the line SFX SilverStone PSUs such as 80 Plus Gold efficiency, modular flexible flat cables, and semi-fanless capability. An ATX adapter bracket is included as well to enable users to install this PSU into any small or even larger cases that do not have SFX mounting holes.

SilverStone SX500-LG V1.1 SFX-L Series Power Supply Key Features:

•    New SFX-L form factor (and ATX via included adapter)
•    Silent running 120mm fan with intelligent semi-fanless operation
•    500W Continuous DC output (up to 40°C)
•    High efficiency with 80 Plus Gold certification
•    100% Modular cables, flat ribbon-style
•    Strict ±3% voltage regulation with low AC ripple and noise
•    All Japanese made capacitors for reliable operation
•    Powerful single +12V rail with 40A (480W)
•    Two PCI-E 6+2 pin connectors
•    Protections: UVP, OVP, OPP, and SCP
•    Universal AC input and Active PFC
•    MSRP $99.99 USD

When you pick up a Kingston HyperX Savage SSD you have a choice of the barebones model at $122 for the 240GB model or you can pay an extra $25 for the upgrade kit which contains 2.5mm z-height adapter, a SATA 6Gb/s cable, a 2.5" to 3.5" adapter plate, Acronis True Image HD imaging software, a micro-screwdriver set, and a USB 3.0 enclosure with USB 3.0 cable.  That upgrade kit is perfect for those looking for an easy way to move their entire OS to the new SSD with a minimum of fuss.  Inside the drive is the Phison PS3110 controller with a 256MB DDR3-1600 cache and Toshiba's 19nm Toggle Mode NAND.  Hardware Canucks put the drive to the test and it shows huge improvements from the first generation, enough to put it in competition with offerings from OCZ, Intel and Crucial.  This demonstrates a faster evolution that competitors products but it does unfortunately come at a price that is a bit high compared to those competitors offerings.
